Typical questions from children and their answers
Here are short and easy answers to the most common questions from our children!
Why do zebras have stripes?
"Mom, why do zebras have stripes?" My daughter asks after the last visit to the zoo.
"Well," I push around, "so that they recognize each other better. No two zebra are the same. "That's true, I've read that at least once.
Nevertheless, I inform myself a little more thoroughly and find out that the question why zebras have stripes has been debated for decades. So I'm not alone with my ignorance.
The main theories of why zebras have streaks are, besides the recognition of the animals among themselves, the following: The streaks would help to regulate the body temperature or would be especially good in hot air and the resulting heat haze in the arid areas a particularly good camouflage. Moreover, when the animals are standing together in a herd, because individual animals blur completely.
The solution is probably, albeit not 100 percent confirmed, much easier. Why zebras have stripes is because they are better protected from tsetse fly attacks. They can transmit dangerous diseases. The compound eyes of the tsetse fly make it impossible for her to see zebras.
Why zebras have stripes is therefore not a whim of nature, but probably a self-protection developed over centuries, as the animals are also home to particularly flies in the regions. The only question now is whether this can also be applied to other insects and whether we should brush in the summer against the annoying mosquitoes just black and white striped once.
Mom, how do whales sleep without choking?
"Mama, how do whales sleep without stifling? They have to take a breath! "
Good question. Unfortunately, I do not know and prefer Google for advice. Whales are mammals. Of course, they have no gills and therefore always have to catch their breath. And this breath does not happen unconsciously as with us humans.
Some whale species can hold their breath for up to ninety minutes, others only manage forty minutes. How whales sleep without suffocating is, of course, a pretty interesting question.
Google teaches me that you have watched the sleep patterns of whales from their small kin, the dolphins. How whales sleep without suffocating can be deduced from these investigations, but it is not quite clear.
Dolphins and orcas always sleep with half of their brains. The other stays awake and ensures that the animals catch their breath in time - in their sleep. One speaks of half-brain sleep. Interestingly enough, one eye remains open, which is opposite to the active brain half. So dolphins are just safe from enemies.
How whales sleep without suffocating is, as mentioned above, not very clear. Sperm whales are known to never sleep more than ninety minutes. But like humans, deep and firm, with both brain halves. But whether all whales sleep in this way without suffocating, one does not know. Some researchers suspect that whales also partially fall into a half-brain sleep. Unfortunately, I can not answer this question to my daughter one hundred percent, but we have learned something anyway!
